To all whom it mayconcern.- t

Be it known that I, JOHN F. LYBRINK, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illi# nois, have`invented certain new and useful Improvements in Mixing-Tanks; andI `dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to mixing-tanks designed especially -for thoroughlymixing varnish, paints, or the like; and it consists of certain novelfeatures of combination and construction of parts, as will behereinafter fnlly described and claimed.

The object of my invention is to provide a mixing-tank which willthoroughly incorpoconstruction of cooperating parts.

ous parts of my invention and coperatingl rate the ingredients employedin producing amost perfect varnish or paint.

A further object of my invention isto ef# feet a thorough mixing of theingredients employed at the expense ofa minimum amount of power. y

Other objects andadvantages will be made fully apparent from thefollowing specification, considered in connectionwith the accompanyingdrawings, in which- Figure 1 is a side elevation ofV my inventioncomplete. Fig. 2 is a longitudinal sec tion of the same on a; reducedscale. Fig. 3

`is a central section of Fig. 2 online `c 0c. Fig.

4 is a similar view to that presented in Fig.

I3, showing the inner blades greatly limited in number and disposed atright angles to `the contiguous surface of the tank. Fig. 5

is a side elevation showing a slightly-varied Fig. 6 is a longitudinalsection of Fig. 5.

In order to conveniently refer to the variaccessories, numerals will beemployed, of which 1 indicates the body portion of my improved mixingtank, which is preferably made cylindrical in form, as shown in Fig. 1,and is so mounted upon the supportingshaft 2 that said shaft will beeccentric to each head 3 of the cylinder.

By reference to Fig. 2 it will be observed that when the body portion ofmy improved tank is disposed in a horizontal position the shaft 2 willextend therethrough on an obany preferred way.

lique line, and in order to prevent leakage around the shaft. I provide4suitable stuffingboxes 4, as clearly shown in Fig. 2, it beingunderstood that when the cap 5 is turned home in its threaded seat thepacking 6 will be thoroughly compressed around the shaft,

'upon the supporting-standards 7, suitably formed and secured in anupright position in One end of the shaft 2 is of sufficient length toextend outward to receive the driving-pulley 8, which is keyed fixedlyto the shaft or theend ofthe journal,

as the case may be, and by means of which power is applied to rotate themixing-tank 1,

`as will be clearly obvious.

I have provided, as shown in Figs. 1, 2, 5, and 6, a suitablereceivingoriiice or mouth 9, having a retaining-cap 10, by means ofwhich the contents of the tank will be held against leakage. A suitableair-vent is provided, as indicated by the numeral 11, said vent beingprovided with a closing-valve 12. I also` provide the faucet 13 and theValve 14:,` `by means of which the contents can be withdrawn at any timewholly or in any desired quantities. I prefer to provide the innersurface of my improved mixing-tank with a plurality of shelf-like blades1.5, preferably extending at right angles to the contiguous part of theinner surface, as fully shown in Fig. 4, though, if preferred, a greaternumber of said blades, as indicated by the numeral 16, may be provided,and said blades may be obliquely disposed` with respect to thecontiguous surface ofthe tank to which they are attached, and while Ihave shown both forms of construction I desire to employ either form asI may see fit in practice to use.

It will of course be understood that the plurality of agitating-blades15 and 16 may be connected to the interior surface of my improved tankin any preferred wayhas, for

. and thus cause the body 1 to turn therewith Ico instance, the same maybe seated in a suitable recess, or said blades may consist of suitableangle-iron properly riveted to the internal walls, as clearly shown inFig. 6.

I have also illustrated that the faucet 13, by which the contents may beremoved in any desired quantities, may be connected directly to one ofthe end sections, though I prefer to connect said faucet upon the side,as shown in Fig. 5, and upon that side of the tank which will be in atrue horizontal position when the tank is at rest. The faucet may beplaced slightly to one side of the central horizontal line, or the innerend of the faucet may extend a few inches, more or less, beyond theinner surface of the side wall, if desired, in order that said inner endwill extend through the accumulation of sediment usually composing thelower strata of the contents, inasmuch as by said arrangement suchsediment may be left undisturbed in the tank, while the contents abovethe sediment may be freely withdrawn. in Figs. 5 and 6 that one of theend sections or heads may be provided with a suitable manhole and aproper closure therefor which will retain the contents against leakage,the object of said manhole being to enable the interior parts to beexamined, repaired, or replaced, as may be necessary from time to timeso to do. The construction of the body portion, as shown in Figs. 5 and6, will therefore be found to be less expensive than the constructionillustrated in Figs. 1 and 2, and I wish, therefore, to reserve theright to adopt either form of construction in practice as I may nd mostdesirable and productive of the best results.

The contents may be introduced into the tank through the receiving-mouth9 and the cap tightly secured in place and the valves 12 and 14 properlyclosed. The pulley attached to the driving-shaft 2 may then be rotatedby any suitable variety of power, when it will be observed that thecontents in the cylindrical body 1 will be most thoroughly agitated andthe component parts thereof commingled with each other to the desireddegree to produce a perfect varnish, paint, or the like. The contentswill not only be engaged and agitated by the plurality of blades 15 or16, as the case may be, but will also be directed by gravity rst fromone end of the tank to the other until the process is complete, when thecontents may be wholly or partly withdrawn, as desired, from the faucet13. It is obvious that in order that the flow Ihave also shown v of thecontents through the faucet 13 may be facilitated the valve 12 may beopened in order to admit the requisite quantity of air into the tank.

Having thus fully described the construction and manner of using myimproved mixing -tank, further reference to the details thereof isdeemed unnecessary.

What I claim as new, and desire to secure by Letters Patent, is

1. The herein-described mixing-tank comprising a body portion, asupporting-journal for each end of said tank disposed eccentrically tothe longitudinal axis of said body portion, with the ends of the tank inparallel planes, and suitable internally-disposed agitating-bladescarried by said body portion, a shaft extending through the body portionand through said journals, supports for said shaft and means forrotating the same, substantially as described.

2. A tank having its ends provided upon the interior with integraljournals disposed eccentrically to the longitudinal axis of the tank,stuffing-boxes upon the outside of the ends of said tank in aline mentwith said journals and a shaft passed through said journals andstuffing-boxes, and secured to the former within the tank, supports forsaid shaft and means for rotating the same.

3. A tank having its ends provided upon the interior with integraljournals disposed eccentrically to the longitudinal axis of the tank,stuffing-boxes upon the outside of the ends of said tank in alinementwith said journals and a shaft passed through said journals andstuffing-boxes, and secured to the former within the tank, and saidjournals being integral with the ends of the tank, supports for saidshaft and means by which said shaft may be rotated.

et. The herein-described mixing-tank comprising a body portion witheccentric journals, a vent at one end, a faucet at one end, a fillingorifice and closure therefor, blades up'on the inner Walls of said bodyportion, supports for said tank, a shaft passed through said bodyportion diagonally to its axis and secured to the body portion, andmeans on said shaft whereby it may be rotated, substantially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.
